Natural light illumination system
Applied Optics, 2010In recent years, green energy has undergone a lot of development and has been the subject of many applications. Many research studies have focused on illumination with sunlight as a means of saving energy and creating healthy lighting. Natural light illumination systems have collecting, transmitting, and lighting elements.

ON Maxwell's theory, lines of electric force which are not anchored to charged particles travel at right angles to themselves with the velocity of light. A circular line of force travelling at right angles to its plane would fulfil this condition and would travel unchanged without loss of energy; it would thus possess one of the properties of the ...

What is light, that wonderful swift carrier of information without which we cannot investigate the depths of the universe nor the secrets of the microworld? For Newton, light was made of particles while Huygens regarded light as waves in a hypothetical medium, the ether.

Light, the first thing as human beings open eyes, is so important to everyone of us. It is also the most mysterious in the universe about which we have seemingly known a lot, but in fact we still know very little. From Isaac Newton's particle theory to Christiaan Huygens' wave theory then Albert Einstein's wave-particle duality, no one has ever told us

AbstractSimulating natural light is an interesting subject in computer graphics. Using the principles of meteorology, we build a sphere cap light source model. Unlike existing illumination or light source models, we consider the effects of both the ratio of direct light to diffuse light and the position of the sun under different weather conditions. We

Lighting device to simulate natural light
2021The present invention relates in general terms to a lighting device to simulate natural lighting, thus capable of generating at least two light components with different angular distributions having different correlated colour temperature or CCT. In particular, the present invention is directed to a lighting device (10,10') to simulate natural lighting
